Title: Improvements in or relating to advancement and spacing of artificial filaments or thread during application of treatment to them
IPC: D01D10/04
Filed: 1945-07-02
Abstract: <PICT:0594384/IV/1> Apparatus for advancing and spacing artificial filaments and threads during treatment in a limited space and providing a self-threading action comprises at least two rollers 1, which may be cylindrical (as shown) or conical, on parallel axes 2 rotating at the same angular velocity in the same direction, at least one of the rollers being formed with ridged portions 3 with their ends smoothed away and disposed so that the grooves therebetween constitute discontinuous screw-threads, the radius of any point at the bottom 5 of a groove being equal to that of the unridged portion 6 of the roller in the plane of rotation containing the said point. The grooved portions preferably all lie as shown in the same segment of the roller.  The direction of rotation of the rollers for right-handed screw-threads is anti-clockwise when viewed from the end where the thread is fed on, and for left-handed threads is clockwise. The distance apart of the rollers is adjusted so that when a closed loop of thread is formed around the rollers and in one of the grooves, rotation of the rollers causes the loop to enter successive grooves until it comes off the ends of the rollers, when it is picked up and the thread end led away over a suitable guide, the oncoming thread 8 being spaced in the grooves as shown.  The closed loop may be in the form of a noose, or may be formed by wrapping the thread several times around the rollers in the same groove.  If the roller system comprises two rollers only, as shown, the length of the grooved portions may be up to half a turn.

Abstract: 603,451. Lathes. RAUSSER & CIE. July 4, 1945, No. 17071. Convention date, Oct. 17, 1944. [Class 83 (iii)] A small lathe, the tailstock of which is adapted to be axially displaced, independently of the position of the main saddle, over the entire length of the bed is characterized in that the main saddle extends below and across the underside of the bed and is guided on both the sides thereof. The lathe bed is of H-shaped cross-section, Fig. 9, supporting a U-shaped saddle 12. The top of the saddle is adapted to take attachments for milling and drilling and has an easily removable cross-slide for facilitating this. The spindle 2 is driven by belt-gearing, Fig. 12, giving stepless speed changes and including an electric motor 7. The expanding and contracting pulleys are spring-pressed together and are carried on the outer members of a stirrup 66 which is rocked to obtain the speed changes by a lever 3. The feed shaft and lead screw are located on the centre line of the machine under the bed, and the drive from the spindle to the former is through a rotatable housing 65, Fig. 11, which is indexible to bring different gear trains into mesh with the spindle and the feed shaft 36. The lead screw is driven from the feed shaft through gearing and a hand control which enables the lead screw to be driven in a forward direction, reversed, or the drive disengaged; additionally, as shown in Fig. 3, the feed shaft 36 may be coupled to the lead-screw nut 45 by sliding the gear-wheel 51<SP>1</SP>, integral with a sleeve keyed to the feed shaft, into mesh with the wheel 45<SP>1</SP> integral with the nut. The control handle 15, Fig. 1, for this operation is linked to a stirrup which at the same time uncouples the nut from its support. Movement in the opposite direction to disengage this drive couples the nut to its housing member so that rotation of the lead-screw by hand or automatically is effective in traversing the saddle. Hand operation of the latter is arranged for by providing a graduated hand wheel 23 on the tailstock end of the lead screw. The tailstock 18 is arranged to traverse the whole of the bed and be fed past the saddle and is located centrally in the bed ways 92, 93, Fig. 9.

Abstract: 689,645. High voltage measurements. SOC. ANON. DES MACHINES ELECTROSTATIQUES. July 10, 1950 [July 15, 1949], No. 17249/50. Class 37. The value of a high voltage is read off an indicator actuated by the output current of a motor-driven electrostatic generator or rotary condenser excited by the voltage undergoing measurement. In Fig. 4, u is the high voltage A.C. or D.C. to be measured. The unearthed side of u charges continuously rotor segments 16 driven by motor 23. The rotor segments 16 alternately register and de-register with stator segments 21 earthed through a bridge rectifier 22 and measuring instrument 10. The stator segments 21 are thus alternately charged and discharged to produce a pulsating output current and the instrument 10 reads the average value of this in terms of kilovolts. The measuring instrument 10 is protected against overloads and surges by neon tubes 25 operating with resistors 24. Further stator plates 20 may be provided intermediate the plates 21 and directly earthed for stabilizing the high voltage input. In modifications, Figs. 1 and 2 (not shown), the unearthed side of u charges the stator segments with the measuring instrument connected to the rotor segments. A wave-trap circuit, Fig. 8 (not shown), may be inserted so that the measuring current varies inversely as the frequency of the mains supply driving the motor 23. A valve amplifier may be inter. posed before the measuring instrument 10. In the practical Fig. 4 equipment, Figs. 5 to 7 (not shown), the electrostatic generator and the driving motor are enclosed in a casing filled with compressed air. The measuring instrument and shunts are enclosed in a separate casing which may be sited remote from the voltage undergoing measurement.

Abstract: 118,526. Fairweather, W., (Singer Manufacturing Co.). June 14, 1917. Button-hole sewing machines.-Relates to buttonhole sewing machines of the type comprising a laterally jogging needle and rotary stitch-forming mechanism, and an intermittently rotated cam-wheel for imparting feeding and lateral movements to the work-holder, and consists in the means for forming the barring- stitches. After the formation of the last depth. stitch t<11>, Fig. 6, of the second side stitching operation and during the succeeding lateral movement of the needle, the work-holder is given a lateral jog in the opposite direction and a fulllength feed to lay the initial barring-stitch t between the point t" and the outer edge of the stitches s of the first side of the button-hole as shown. The work-holder then receives step-bystep reverse lateral movements, and the stitchforming mechanism rotary movements in the opposite direction to the rotary movements performed in stitching round the eye of the buttonhole, to lay the intermediate barring-stitches t<1>, after the final depth stitch puncture of which at t<13> the work-holder is given a full lateral jog in the same direction as the initial lateral movement to bring the work to the central position. During the formation of the barring-stitches, the workholder may be given a reduced feeding movement in the direction of the length of the button-hole, so that the outer line of the barring-stitches, during formation, may be slightly curved and, on tightening up the stitches, assume a substantially straight-line position transverse to the buttonhole, owing to the yielding of the fabric. The cam-wheel 26, Fig. 2, by which the feeding and laterally jogging movements are imparted to the work-holder and the rotary movements to the stitch-forming mechanism, is rotated step by step by the shaft 19, which is intermittently rotated from the main shaft 10 by an intermediate shaft carrying a disk 15 with two eccentricallyarranged pins 16 engaging teeth 22 on a disk 21 secured to the shaft 19. The teeth are formed at their outer ends with parts which are engaged simultaneously. with the pins 16 and, in this position, are concentric with the axis of rotation of the pins, and on their inner ends with inclined parts which are engaged by the pins alternately to produce the intermittent movement of the shaft 19.
